Obesity remains a serious health problem and it is no secret that many people want to lose weight. Behavioral economists typically argue that “nudges” help individuals with various decisionmaking flaws to live longer, healthier, and better lives. In an article in the new issue of Regulation, Michael L. Marlow discusses how nudging by government differs from nudging by markets, and explains why market nudging is the more promising avenue for helping citizens to lose weight.

Two long wars, chronic deficits, the financial crisis, the costly drug war, the growth of executive power under Presidents Bush and Obama, and the revelations about NSA abuses, have given rise to a growing libertarian movement in our country – with a greater focus on individual liberty and less government power. David Boaz’s newly released The Libertarian Mind is a comprehensive guide to the history, philosophy, and growth of the libertarian movement, with incisive analyses of today’s most pressing issues and policies.

Munich All over Again (and Again, and Again)

Although it is likely to get lost amidst the brouhaha over the proposed bailout, Geoffrey Wheatcroft’s article ”‘Munich’ Shouldn’t Be Such a Dirty Word,” in the Washington Post’s Sunday Outlook section is worth reading now, and storing away for future reference. (And, in case you missed it, also revisit Justin Logan’s article on the overuse of the Munich analogy.)

Advocates for preventive war and pledges of military support to would-be client states routinely invoke the Hitler/Chamberlain/Munich analogy, and heap scorn upon those who favor negotiations as naive appeasers. When every potential adversary who we might engage, from Mahmoud Ahmadinejad to Hugo Chavez, can be cast as the second coming of Adolf Hitler, what point can there possibly be in talking with such men?

Uber-hawk (and John McCain adviser) Robert Kagan offered the latest exhibit in the prosecution’s case against diplomacy by claiming that Russia’s attack on Georgia was comparable to the “Sudeten Crisis that led to Nazi Germany’s invasion of Czechoslovakia,” even though “the precise details” of the Russian-Georgian clash were not known.

I have long been skeptical of such claims, in part because they are cast about so often, and also because it is so easy to misconstrue historical analogies. Kagan’s certitude notwithstanding, the details do matter, but are usually papered over by those making the case for forceful action. The great diplomatic historian Ernest R. May made this point eloquently in his book “Lessons” of the Past, and later with Richard Neustadt in Thinking in Time. With respect to that most-overused analogy, Wheatcroft has provided still more ammunition for those of us willing to dissent when the people around us seem hell-bent on war.
